IEEE defines software design documentation as 'a description of software created to facilitate analysis, planning, implementation, and decision-making. This design description is -used as a medium for communicating software design information and can be considered as a blueprint or model of the system.

A test case provides the description of inputs and their expected outputs to observe whether the software or a part of the software is working correctly. IEEE defines test case as 'a set of input values, execution preconditions, expected results and execution post conditions, developed for a particular objective or test condition such as to exercise a particular program path or to verify compliance with a specific requirement.' Generally, a test case is associated with details like identifier, name, purpose, required inputs, test conditions, and expected outputs.

For effective project monitoring, the information coming from the development process to the management process should be objective and quantitative data about the project. Software matrices are quantifiable measures that could be used to measure different characteristics of a software system or the software development process.

Once a system has been deployed, new requirements inevitably emerge. It is difficult for the users to anticipate the effect of these new requirements (if a new system is developed for these requirements) on the organization. Thus, to understand and control changes to system requirements, requirements management is performed.

Studies suggest that the software maintenance process begins without proper knowledge of the software system. This occurs because the software maintenance team is unaware of the requirements and design documentation. Also, traditional models fail to capture the evolutionary nature of the software. To overcome these problems, software maintenance models have been proposed, which include quick fix model, iterative enhancement model, and reuse-oriented model.

Having test cases that are good at revealing the presence of faults is central to successful testing. Ideally, we would like to determine a set of test cases such that successful execution of all of them implies that there are no errors in the program. This ideal goal cannot usually be achieved due to practical and theoretical constraints.

Over a period of time, the developed software system may need modifications according to the changing user requirements. Such being the case, maintenance becomes essential. The software maintenance process comprises a set of software engineering activities that occur after the software has been delivered to the user.

There are two basic approaches to testing: functional and structural. In functional testing   the structure of the program is not considered. Test cases are decided solely on the basis of the requirements or specifications of the program or module, and the internals module of the program are not considered for selection of test cases.

There are a few techniques available to verify that the detailed design is consistent with the system design. The focus of verification in the detailed design phase is on showing that the detailed design meets the specifications laid down in the system design. The three verification methods we consider are design walkthrough, critical design review, and consistency checkers.
